Uninstall → It is formed from "un-" (meaning not or opposite of) and "install" (from Latin "instalare", meaning to place or set up). The word "uninstall" means to remove or set something down that was previously installed.
Think of 'un-' meaning not or the opposite, and 'install' meaning to set up. So, uninstallation is like taking something that was set up and removing it.
